Answer: < 10, 5 >
===============================================
Let a,b,c,d be scalars.
In general if v and w are two vectors such that
v = <a, b>
w = <c,d>
then the difference of the two vectors is
v - w = <a-c, b-d>
so we subtract the coordinates
-----------------
Using that idea for the given vectors leads to
v = <9, -1>
w = <-1, -6>
v - w = <9 - (-1), -1-(-6)>
v - w = <9+1, -1+6>
v - w = < 10, 5 >
